Right, but thats still twice the cost of buying 2 smaller PSU. I was just pointing out that you can get to the same result by buying 2 smaller PSU instead of one big PSU that is worth 5 smaller PSU.

You're paying premium for 93%~ eff instead of 91%~ efficiency and for having the watt support in one unit instead of two.

For instance for under 300$ you could get 2 EVGA GS 1050W which would give you 91.0%+ Efficiency vs the AX1500i's 92.2% for 400$~ And it goes down to 200$ if you're okay with the efficiency dropping to 90% by getting 2 750W PSU, or 240$ for 2 850W PSU.


Same answer as above, you'll have more stable voltage and less psu strain and much better headroom if you go for 2x PSU and for cheaper. You could go with 2 smaller Plat PSU if you wanted to get better efficiency than the AX1500i and it would still be cheaper and you would still have better headroom.

Thank you for posting! I think I seen my miner  sitting there 😉

I have many many many many many many many psu's  and I should use many a few more times.

s-7 runs great with the evga 1600 p2

I am running on it as I type.

but it is costly psu.

the s-7 run goods on the evga 1300g2

when I was running 2 s-7's I used it along with the  1600 watt platinum.

should you use the cheaper one? well I could argue no go for the plat.

this one is the price for two 1000 watts...evga or corsair  and get 9/9 from johny

Thats a decent PSU but the price is out of this world. You can do better with 2x750-1050 EVGA P/G2/GS From one third the price to half the price for near or same efficiency depending on whether you get G or P.

The G2/GS are so popular because they push nearly Platinum efficiency and the price is right.

Could power the S7 for 150$ no problem with 10 or 7 years warranty.

10 PCI-E output, 10 PCI-E cables, up to 125 amp. 7 year warranty-most important
i think ,sustained over a longer life than the whole life of one S7 

I have many years of good experience with these http://www.guru3d.com/articles-pages/corsair-ax1200i-psu-review,9.html

Mine was more than happy at 675, although I'm at stock now for noise levels. See the hash rate / power / temp / clock speed graph in my guide. tldr though is if you don't care about warranty then any overclocking headroom is free (risky) money due to the linear power consumption of fixed voltage..

No, they have not "said" they will give coupons out.  Does this mean they will not give them out because they have not said it?  No.

For instance, I told my client 15% less on my service for delaying them a week.  They accepted...  I also gave them a 15% discount on the next week they scheduled from me after completing the first week.  I offered this "after" completing the first week.  I did not tell them this before the first week.

I've been given more compensation than what I was told originally by venders several times in my business dealings in the past.  I'm a contractor for land line telephone companies in the U.S.  I teach their technicians how to use their meter to identify and locate troubles.  I also consult with training departments to help them be more affective.  I've had business dealings with various vendors for my training boards I've designed and built.  Over 200 solder connections in each training board that simulates 19,700 feet of 24 gauge/ Air Core Cable [Not jelly filled].  Jelly filled is .092 uF per mile/.0174 uF per 1000 feet and Air Core is .083 uF per mile/.0157 uF per 1000 feet.  They've been late before and gave me more compensation than what was originally stated.

Will BITMAIN do this?  I don't know.  Only time will tell.  However, I'm NOT going to be rude while waiting on compensation.  Being rude may very well ensure hate and discontent of both parties and reduce the chance of a more profitable compensation.

I've learned through my business dealings, it's just not profitable to draw conclusions and "react" on those conclusions drawn without an actual "conclusion."

EDIT:  I'm about to take a shower and meet my wife downtown for lunch.  So, I will not be able to check back in for a while.

Where are you getting that there might be compensation with coupons?  If they followed past and did decent coupons yes it could be a much better compensation then what I thought I read.

I thought I read it was like the amount it would have made on PPS till it ships.  And you don't get paid for time in shipment only till it ships.  I don't see where they left it open for coupons unless I missed a post from BM.

I have no idea what was "weighed" in their mind when deciding shipment dates.  It's actually quite possible they did not take the time to do quality control checks the way they should have because of less employees due to low bitcoin price.  They may have "intended" to have a certain number of rigs manufactured and shipped before that holiday but ran into a series of unfortunate events.  Which ended up going all the way to the holiday.

In the future, I believe they will allow extra days for possible "unfortunate events" [That do not fall during a holiday].  As for "... they learned they can do low compensation," I have not seen the compensation yet.  So, I'm not going to comment on the compensation until it is delivered to those who deserve it.  This compensation may also include a $100 coupon for each rig that was ordered.  If one cannot use the coupon, they can sell it.

I realize everyone does not have the same situation.  Some have free power and I can see where the compensation would not be as attractive to them as it would be for others who may pay $0.10 kWH.  Those people would have to decide for themselves if they wish to continue business with BITMAIN in the future.  If they do wish to continue business in the future, it does not help them in the least to be rude.

I personally feel we should be allowed to get the rigs for the same price as batch 3.  Will the compensation with possible coupons be close to that?  Only time will tell.  

As promised, here are more photos from the Shenzhen facility of Bitmain. Thanks again for their hospitality. I have a video of their miners hashing aswell, I'll upload it later on.

They said they were busy with packaging the miners and shipping them. I hope you guys get yours soon too.

I agree name calling is not going to help, and might as well stay cool and level headed.   But Bitmain took a holiday during a batch before it was done.  Understandable they would want time with family over holiday, yes hard to fault the workers there.

But the compensation they have mentioned is pretty horid.  They waited and released it during a weekend, which I think was done so they did not have to hear be at work during first wave of angry customers.

What do you think they will learn from this?  i mean they learned they can do low compensation, and little communication.   I don't think it was a good learning experience.

I understand your reasoning there.  I think I voiced something similar earlier in the thread.  I appreciate your calm attitude while voicing your opinion without name calling.  I think it's wise for all us to remain calm and patient to see what "compensation" is to come.  They might even throw coupons into the mix with the "compensation" for those who had late shipments and/or rigs below specifications.  I'm just going to be patient and allow them the opportunity to make good on their period of unfortunate events.

Could they have been better with communication?  Yes.  Will they learn from this?  Yes, I believe they will.  Only time and patience will tell.

Cheers M8

EDIT:  They are probably short handed, especially with the price of bitcoin these days.  They have batch 2 and 3 orders [/b]to fill; quality control with board testing, etc...  I can only imagine what all they have to do right now.  Especially, after awakening to the defective boards.  They may have decided to focus more of their time [With limited man power] on testing boards and shipping, than taking the time to look up the email for each order yet to be filled and sending them communication to apologize for the delay with explanation for compensation.  We have no idea how stressed they may be at this particular time with this unfortunate mishap.  In time, we may find their quality and communication improved through trials and errors.

I agree but batch 2 is @$250 cheaper. It will be hard to justify the higher price for batch 1 which has not shipped yet, even with the .027 compasation.

Yes, more QA taking place.  I wish people would refrain from rude comments without giving BITMAIN the opportunity to follow through to completion their "compensation" for those who had to wait.  They may find themselves regretting their rude comments later on.  I understand their disappointment cause I'm still waiting for close to $20K worth of S7's myself.  However, I feel one should still remain "professional" if and/or when problems arise to avoid stress, regrets, burning bridges, etc...  

I have run my own business for quite some time now [Since 1997].  I've had my own share of regrets when saying things I should not have said and doing things I should not have done.  I ended up learning "the hard way" from my own mistakes and times of lacking patience in the past.  I've become a bit more mature in my business dealings with age.

I know of a time when I failed to meet a deadline for a customer and held them up for one week.  The dude cursed me out over the phone [But I remained calm and consoling].  I ended up making it up to him without getting irate back at him and avoided burning bridges.  He ended up apologizing for his rude comments and we ended up being good friends to this date and we play golf together on occasions.

I'm saying all of this just to say we might want to give BITMAIN full opportunity to make good on their unfortunate events that have occurred as of late without being rude.  If they had messed up, I think they would like the opportunity to make good on their mess up without being railed upon.  Being rude doesn't help anything.  It only fuels more hate and discontent [Possibly from both parties].  I can understand "chewing someone a new ass" if that particular someone has been a complete ass hole.  However, I'm not necessarily condoning "chewing a new ass" either.  

Patience, truly is a virtue!  If things do not come out as hoped, I still believe karma bestows what is deserved in the end for both parties.  It's okay to have a grievance where it is due.  I just believe those grievances can be voiced without being rude.  There was a time when I would chew someone a new ass like a Marine drill instructor.  I've found [By learning the hard way through the years] is best to try to refrain and be the better person if you can, especially in business dealings.  Doing so [I've found] can be imbibed from the receiving party and end up being fruitful for both parties in the end.

Cheers M8's  

If you think about it, batch 2 IS batch 1.
